The detailed magnetic survey was carried out using a SENSYS MAGNETO MXCOMPACT 7 channel cart-based system. The instrument has 7 fluxgate gradiometers (FGM650) spaced 0.5m apart with readings recorded at 20Hz for Areas 1, 2 & 4 and at 100Hz for Areas 3, 5 & 6. This equates to a survey resolution of 0.5m by c0.15m. The results indicate the presence of anomalies of archaeological potential in the southern part of the site that appear associated with industrial activity. To the north, the majority of the anomalies are associated with naturally formed features and extant and infilled drainage channels or grypes. A small number of positive linear anomalies have also been located, but these lack a clear morphology.
